ALMON T. MORRIS, OF TIFFIN, OHIO.

SAWlNG-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 234,886, dated November30, 1880.

Application filed August 9, 1880.

To all whom it may concern Be it known that I, ALMON T. MORRIS, ofTiffin, in the county of Seneca and State of Ohio, have invented certainnew and useful Improvements in Sawing-Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accom panyin gdrawings, which form part of this specification.

1n the drawings, Figure 1 is a view, in side elevation, ofasawing-machine constructed according to my invention. Fig. 2 is a planview of the same.

A represents the log in process of being cut. B represents the saw; 0,the pitman connecting the saw with the pivotal lever D. This pivotallever D is pivoted to the uprights G at d. One arm ofthe pivotal leverbeing connected directly to the pitman O, and also to the end of thelever H, the other arm of the pivotal lever is connected with thehand-lever near the handle by means of the connectingrod E.

G G are two uprights, adapted to support the pivotal lever D and permitthe same to operate between them. K K are frame-pieces extending fromthe uprights G G to the log. They are pivoted to the uprights G G at It,and are adapted to be raised or lowered at their outer extremities, asthe size of the log may requlre.

L is a strap pivoted to the top of the uprights G G, and at the otherend attached removably to the frame K K, to which it is also pivoted. Itmay be provided with several pinholes, l, which will permit of itsconnection with the frame-pieces K K.

At the other extremities of the frame-pieces K Kand over the log isattached the headblock or guide M, through which the saw travels untilit is buried in the log. This head-piece or guide M keeps the saw in itsproper place as it begins to enter the log.

For the purpose of temporarily attaching my saw-frame to the log, Iprovide a device very much like an ordinary cant hook, as

. shown in Fig. 1, at N. It consists of a lever,

N, pivoted to the frame-piece K at n, and provided with a hook, N. Atits outer extremity,

(No model.)

and upon the under side of the lever N, it is also provided with aspike-pin, 12

When the hook N is driven into the log for the purpose of holding it toits proper position the lever N is sustained by the pin a in theframe-piece K.

To assist in steadying the saw, and also to add weight to it at thepoint where it comes in contact with the log during the operation ofsawing, I provide a rod, R, pivoted to the upright G, and having itsother extremity resting upon the top of the saw immediately over thelog. This rod may have a single arm attached to one of the uprights G,or it may be provided with two arms attached to the uprights G G.

P is a lever, pivoted to the foot of the upright G, at one end of whichis attached an arm, P. The upper end of this arm P is attached to theupright G.

The object of this portion of my device is to steady the frame-work ofthe machine during the operation of sawing, and is accomplished byplacing the foot upon the outer extremity of the lever P, as shown inFig. 1, when the base supporting the uprights G G will act as a fulcrumfor this lever P, which, at its other extremity, is hearing against thearm P, and is connected with the upper portion of the upright G.

The operation of my device is as follows: The head-piece M is placed onthe log at the point where the same is desired to be out. The lever Nbeing free, the point of the hook N is placed against the log. Thespike-pin a rests upon the top of the log. The lever N is now raised,when the hook N is driven into the lower portion of the log and thespike-pin n is forced into the top of the log. The lever N is now heldin position by the pin a in the frame K. The rod R is dropped upon thesaw B, where it adds weight and materially assists in cutting. The footof the operator is placed upon the lever P, as shown in Fig. 1, whichoperation, through the lever P, steadies the top of the machine. Thehandle H is now manipulated until the log is sawed in two, when theoperation is repeated.

By placing the pivot 01 at or near the under side of the pivotal leverD, as shown in Fig. 1, the saw is more quickly raised, and this avoidsthe necessity of a handle, H, passing through the distance otherwiserequired to give the same length of sweep to the saw.

What I claim is 1. The combination, with the bar K, pivoted at one endto the standard G, the free end of said bar adapted to rest on the log,of the can thook lever N, pivoted at one end to the bar K,

said cant-hook lever having a cant-hook, N,

pivoted thereto and provided with a stud, a on the lower edge of itsshort arm, and a stud, n inserted in the bar K, for retaining the longarm of the cant-hook lever in place, substan tially as set forth.

2. In a sawingmachine, the combination, with a vertical lever having itslower extremity pivoted to the saw-shank, and its upper extremityprovided with an extension in rear of its fulcrum, of a handle havingits forward extremity pivoted to the lower portion of the lever, and aconnecting-rod having its upper extremity pivoted to said rear extensionof the lever, and its lower extremity pivoted to the rear portion of thehandle, substantially as set forth. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
